STUM P-EXTRACTO R.

EEPECIPICATION forming part of Letters Patent No. 393,541, dated November 27, 1888.

Application filed March 1, 1888.

To aZZ whom, it may concern- Be it known that 1, JOHN CORNELIUS, of Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Improvement in Stump Extractors, of which the following is a specification.

My invention is an improvement in stumpeXtractors,and seeks to provide improvements whereby the machine will be strong in operation and easily adjusted in position for use; by which the chain will be accurately guided into the guidepulleys with its links properly presented to enter between said pulleysin the manner desired; by which the chain when it has been drawn up to the machine in pulling a stump may be quickly adjusted out to position for drawing another stump or stumps,and to so arrange the parts that the power of the operating-worm will be applied on opposite sides of the clrainwheel.

The invention also seeks to provide other -improvements; and it consists in certain features of construction and novel combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a plan view of the machine, parts being removed and others shown in section. Fig. 2 is a section of the machine on about line .22 m, Fig. 1. Fig. 3 is a detail View of the worm supporting lever. Fig. 4 is a detached section on liney y, Fig. 1. Fig. 5 is a partial front View of the machine.

In the construction shown the framing consists of the sides A A, the runners B B, secured below and extended at their ends beyond the said sides, and the front and rear top beams, O D.

The runners B B are set a considerable distance apart, forming a space between them, in which space I support rollers E E, arranged between the runners near their ends and extended slightly below such runners, as shown. These rollers coact with the runners in supporting the machine, so it can be conveniently moved, the rollers on a smooth hard surface bearing the weight of the machine, while on a soft or irregular surface the machine can be easily moved on the rollers and runners. It is preferred to support the roller E so the supports therefor will in a measure brace the runners. To this end I form such rollers with Serial No. 265,869. (No model.)

axial openings 0, and, the rollers being preferably of wood, place metallic bushings e in such openings 0 at theends of the rollers. I also )rovide tires or rims c" of metal encirclin 7 7 b u the ends of the rollers. The rods E E, on which the rollers turn, are extended through the runners B B and through the openings 6 of the rollers, the said rods being suitably held on the outer sides of said runners, as shown. These rods, it will be seen, in addition to form ing bearings for the rollers, serve as braces between the runners and aid in strengthening the machine.

The horizontal or main shaft F is supported at its ends in the sides A, preferably being journaled in boxes a, secured in said sides and having lugs a, to which the anchor-bail a may be connected. On this shaft F, I support the chain-wheel G and the worm-wheel H, which latter is, by preference, formed in two sections, l1, such sections being arranged on opposite sides of the chain-wheel,and are fixed as to rotary movement with reference to the said chain-wheel. The chain-wheel and sections may be fixed on the main shaft, as shown; but manifestly it would involve no departure from my invention to journal such parts on the shaft. By preference the chain-wheel and worinwheel are cast or otherwise formed in a single piece, the worm-wheel sections being formed on the opposite sides of the chainthe worm-wheel sections is insured, and the number of parts is reduced, rendering the machine simpler, as will be readily understood.

The chain-wheel and worm-wheel sections form what may be called a combined worm and chain Wheel, the chain-wheel being suitably pocketcd at g and grooved at g to properly receive and grip the links presented sidewise and edgewise thereto.

The described arrangement of the wormwheel sections secures an equal distribution of power on opposite sides of the resistance ex erted against the chain-wheel and renders the operation of the machine smoother and easier. The worm H is formed and arranged to mesh with the worm-wheel. I support this worm in bearings I in lever I, which lever is pivoted or hinged at one end to one side A, and extends at its opposite end to and usually past the opposite side A, and is secured by a suitable fastening, 2', usually a hook, as shown.

By throwing this lever in and out the worm may be thrown into and out of gear wit-h the worm wheel, so that when the end of the chain has been drawn up to the guide-pulleys in IO pulling a stump the worm may be thrown out of gearwith the worm-wheel and the chain drawn rapidly back through the machine to position for starting another stump.

The arrangement of the leverIshown is very x5 simpleand provides a construction which requires but little force or strength to properly move the worm into and out of mesh with the worm-wheel. I prefer to house or case the chain-wheel in at J around its rear side and provide guides or ways K K, leading forward from the under and upper side thereof, through which the chain is directed to and discharged from the machine in the operation of pulling a stump. The lower way, K, leads to the guide-pulleys L, which are supported in a frame, M, consisting of a base-plate, m, standards m thereon, and a top plate, m, mounted on said standards and bolted securely thereto, the pulleys being supported between the base 0 and top plates, and being, by preference, journaled on bolt-like rods Z, which extend between the front runner and front top beam and serve as braces for such parts of the machine.

On the top plate, m", of the pulley-frame M,

I cast or otherwise form two upwardly-proj ected parallel plates, N N, slightly separated to receive between them the plate 0, east on the under side of the guide-tube K, and having its upper and lower rear corners at 0 0 ex- 0 tended into the basegroove of the chain-wheel to strip the chain therefrom in' the operation of the machine in either direction-that is to say, in drawing the chain through the machine in pulling a stump or in the reverse direction,

4 5 as when the chain is being returned through reversing the movement of the sweep, thus preventing any clogging and the consequent possibility of breaking or damaging the chain or parts of the'machine.

The plate 0 is bolted securely between the plates N, and is thereby held in position, the

plate 0 serving as a support for the upper tube and being extended to form the stripper for clearing the chain from the chain-wheel.

When the heavy chain is drawn rapidlythrough the upper way or guide-tube, K, in

returning the chain after a stump has been pulled, there is considerable strain on such tube, to obviate which I provide a crossbrace, P, extended between the sides A, near the for 6 5 ward ends thereof, which brace extends under and supports the tube K, such tube being secured by a cap-piece, p, fitted over it and secured at its ends to the body or main portion of the cross-brace. This brace holds the tube K firmly and enables the same to be made of much lighter metal than would otherwise be practicable.

In order to direct the chain properlyto the guide-pulleys, as in taking up slack preparatory to pulling a stump, I provide an inclined platform or bearing-plate, Q, formed, preferably, integral with the lower plate of the pulley-frame and leading up to such pulleys, as shown, in moving up which platform the links will assume the proper position to enable their presentation to the pulleys in the desired manner.

In operation the machine is anchored in position at its rear end, and the chain leading out from the guidepulleys issecnred to one or more stumps, as desired, and power is applied usually by hitching a horse or horses to the sweep secured on the upper end of the worm, the latter being properly meshed with the worm-wheel. Then the machine will be drawn to face the direction of greatest strain, and as one, two, or more stumps of a group are pulled it will from time to time change its position to facethe direction of greatest strain, as will be understood from the drawings.

\Vhen the stump or stumps are pulled and the chain is drawn up to the guide-pulleys, a horse or horses may be hitched to such end of the chain,the worm be thrown out of mesh with the worm-wheel, and the chain be quickly drawn back through the machine.

A sweep, II, indicated in dotted lines, Fig. 1, and full lines, Fig. 2, forms a convenient means of applying the moving force to the.

worm.

Having thus described my invention, what I claim as new is- 1..
